Application January 19, 1933, Serial No. 652,537 In Germany March 21, 1932 '7 Claims.

This invention relates to cash registers and the like and has for its principal object to design a machine adapted to issue differently characterized checks from one paper ro Another object of this invention is to construct the check printing device in such a manner, that the check issued either at will or in certain fixed cases is covered with-a coloured impression over the' normal data as amount, name of the firm,

consecutive number, etc.

The present inking device can also be built in such a manner that the check is covered with a special impression not only on one side'but also on both sides without influencing the nature of the invention.

A preferred form of embodiment of the device is hereafter described with reference to the drawings, which accompany and form part of the specification.

Of said drawings,

Figure 1 is a transverse section across the printing device,

Figure 2 is a front plan view of the printing device, partial transverse section across the ink- 25 ing device,

Figure 3 is an ordinary check, and Figure 4 is a checkwith a special impression over the normal impressions.

The check strip 2 supplied by the paper roll 1 30 is led through the paper guiding device to the feed and printing rolls 4 and 5 respectively (Fig. 1). It thereupon runs between the printing type wheels 6 and the printing hammer 7 to the cut-off attachment. This device consists of a round knife 8 and a flat counter knife 9. By means of a spring, not shown in the sketch, the latter knife is pressed against the round knife 8. The paper strip passing the round knife 8 runs through the paper guiding device between the feed rolls 49 11, 11a and the feed cylinder 12. Arranged between these feed rolls is a printing cylinder 13 fitted with an electro showing a hatch (Figures 1 and 2) This printing cylinder is pivoted on an eccentric 14 of the axle 15. Fitted on the axle 45 15 carrying the eccentric 14 is an arm 16, the lateral pin 1'1 of which engages the fork-shaped upper end of the leverv 18 which is rotatably se-- cured to part 19. The arm 18 is fitted with a roller 20 engaging a curved cam slot 21 of a seg- 50 ment 22. This segment is set in conjunction with the special letter type wheel by setting means, for example, by a setting lever s as shown in dotted lines in Fig. 1, which is set according to the transaction to be registered by the machine. 55 For the form of embodiment shown, the curved tioned special impression is issued, whereas slot or cam of this segment is formed in such a manner that only in one position of the curved slotted segment 22 a check covered with the menall other positions of the said segment no special printing occurs. The operation of the feed rolls 4 and 5 and also 11 and 12 respectively is effected by the main shaft 23 of thecash register (Fig. l). Fitted to this main shaft are a large gear 24 and a small gear 25. The gear 24 is in mesh with two gears mounted on the feed rolls 4 and 5 and gives the latter one, if actuated by the main shaft, one complete revolution. By means of the inter,- mediate gears 26, 2'7 and 28 the small gear is in mesh with the driving gear 29 rotatably secured on the shaft 15. The latter gear 29 is coupled with the feed roll 11a which is fitted with a pin 30 meshing with a slit-shaped recess 31 of the printing cylinder 13 (Fig. 2). The other end of the printing cylinder 13 shows a similar slitshaped recess 32 engaged by a pin 33 of the feed roll 11. Through the pins 30 and 33 and the slitshaped recesses 31 and 32, the turning movement of the feed roll 11a, if actuated by gear 29, is transferred to the printing cylinder 13 and therefrom to the feed roll 11. The slit-shaped recesses 31 and 32 guide the printing cylinder 13 in its movement upwards and downwards to and from the feeding cylinder 12.

The inking of the printing cylinder 13 occurs 35 by means of an inking roll 34 turning loosely on a shaft 35. The latter is pivoted in two arms 36 and 36a fastened on the shaft 3'7. The shaft 3'1 is rotatably secured in the machine frames 38 and 39 and carries in addition two arms 40 and 40a which are subject to the action of two springs 41 and 41a. By the aid of a system of sleeves the type printing wheels 6 are associated with the gears 42 working in conjunction with the setting mechanism of the cash register. This device is generally known and therefore not represented in the drawings.

The feed roll 4 (Fig. 1) is also used as a printing cylinder. In the present case it serves the purpose of printing the full date together with the denomination DRK on the check. For the purpose of inking the aforesaid roll there is an inking cylinder 43 which is pivoted in a supporting lever (Fig. 1).

The inking of the printing types 6 is effected 1 by means of an ink ribbon 45 which is marked in Fig. 1 by a dot and dash line.

The device works as follows:

In the first phase of the machine operation the printing wheels are set by the gears 42 according to the keys pressed On machines which are set by levers, the printing wheels are set before the handle is turned i. e. immediately upon displacement of the setting levers. The printing hammer 7 enters into operation immediately the printing wheels are set and prints the set types on the paper strip.

The feed rolls 4 and 5 have meanwhile turned so much that the feed edge 4a seizes the paper strip 2. By means of the feed cylinder 5, made of elastic material the paper strip is now forwarded and printed at the same time with the date and the designation DRK. The strip leaves the round knife 8 through the paper guiding device 10 and is led to the feed rolls 11, 11a and to the feed cylinder 12. The forwarding efiect of the feed cylinders 4 and 5 upon the paper ceases immediately the paper strip reaches the feed rolls and by the aid of the round knife the check is out.

In the moment when the check is cut, the ele vated surface of the printing cylinder 13 has turned around by so much that it reaches the counter printing cylinder 12. As it was inked by the inking cylinder 34 shortly before, the check is covered with a shading impression as shown in Fig. 4. The check thus printed can now be taken from the machine. The hatched impression on the check takes place only if the segment with the curved slot is in such a position that the roll 20 is in the place 21a of the curved slot 21. In all other positions of the segment 22, the eccentric 14 occupies a position as shown in Fig. 1. In this position the printing cylinder 13 is removed from the counter cylinder 12 to such an extent that no hatched impression occurs on the check.

This displacement of the cam segment can also be eifected through a special manipulation. In this case it is possible to get checks issued with and without the hatched impression, viz., in full independence of the remaining mechanism of the machine.

What I claim is:

1. In a machine of the class described, a plurality. of type carriers adapted to print a check strip, means for taking an impression from said type carriers on said check strip, means for feeding said check strip, printing means for taking a second impression over said first impression, and means for rendering effective said last-mentioned printing means.

printing cylinders, a setting lever, said second feeding means and printing cylinders eifecting a second impression over said first named impression in one of the positions of said setting lever.

3. In a machine of the class described, a supply roll for a paper strip, feeding means for said paper strip, type carriers, means for taking an impression from said type carriers, a cut oii attachment for said strip, second feeding means combined with printing cylinders adapted to take a second impression over said first named impression, and means for rendering effective or inefiective said second printing means.

4. In a machine of the class described, printing means adapted to make an impression on a check strip, second printing means for making an impression over said first impression, setting means, and means operated by said setting means adapted to render inefi'ective said second printing means.

5. In a machine of the class described, printing 109 means adapted to make an impression on a check strip, second printing means for making animpression over said first named impression, said second means being combined with feeding means for said check strip, means adapted to render ineflective said second printing means but not influencing said feeding means combined with said second printing means.

6. In a machine of the class described, printing means adapted to make an impression on a check lid to render ineffective said second printing means but not said feeding means.
